Abstract: 1,025,039. Protective systems. TRANSELEKTRO MAGYAR VILLAMOSSAGI KULKERESKEDELMI VALLALAT. Sept. 25, 1964, No. 39290/64. Heading H2K. [Also in Division G4] A condition indicating arrangement comprises a pair of parallel paths each including a resistor and a switch R 1 , K 1  and R 2 , K 2  respectively and a gas-discharge tube G connected between the junction points C 1 , C 2 . In one condition switch K 1  is open and K 2  closed, and current flow between terminals T 1 , T 2  causes one of the tube electrodes E 1  or E 2  to glow. In a second condition, K 1  is closed and K 2  open and current flow through tube G is in the other direction causing the other electrode to glow. Two further conditions may be indicated by means of a further switch N which connects an A.C. supply Sz to one or other electrode of the tube. Four indications are thus obtained, i.e. a steady or pulsating glow on either electrode E 1  or on E 2 , depending on the positions of switches K and N. In a modification, Fig. 2 (not shown), the diodes D 1 , D 2  are omitted and contact 3 of switch N is connected via a capacitor to terminal T 1 , thus forming a self-oscillating circuit when ever the switches connect the capacitor across the tube G.

Title: Solid state electric cell having stabilized resistance
IPC: H01M6/18
Filed: 1971-08-23
Abstract: 1366535 Solid state cells GOULD Inc 23 Aug 1971 [31 Aug 1970] 39469/71 Heading H1B In a solid state cell a getter is provided in the electrolyte to prevent a mobile cathode oxidant, e.g. a halogen or sulphur, from reaching and reacting with the anode to form a high resistance layer thereon of, e.g. AgI. Where the mobile oxidant is iodine the preferred getter consists of silver which is dispersed in the solid electrolyte whereby the iodine is retained by reacting to form AgI. Since the AgI is dispersed in the electrolyte it leaves conducting paths therethrough and the cell resistance is not increased. Alternative getters are Cu, Te, Ag 2 S, CU 2 S. In another method, the electrolyte includes a getter material which reacts with the mobile oxidant to form a complex therewith, e.g. a halide salt capable of polyhalogen formation, viz. (CH 3 ) 4 NI, (C 4 H 9 ) 4 NI, (CH 3 ) 3 SI. Further, in another method, the electrolyte includes as getter a charge transfer complex, e.g. a hexamethylenetetramine quaternary salt of a halogenated allyl halide, which reacts with the iodine. The solid electrolyte preferably consists of RbAg 4 I 5  and a resin binder together with the getter material, e.g. Ag. The preferred anode material comprises a mixture of Ag, RbAg 4 I 5  and C and the preferred cathode material comprises a mixture of (CH 3 ) 4 Nl 9 , RbAg 4 I 5  and C. In the embodiment shown in Fig. 3, the electrolyte comprises two layers 25, 27, the layer 25 adjacent the cathode 17 not including the getter material whereas the layer 27 has silver 23 dispersed therein. The anode 13 is in contact with a silver layer 11 and the cathode 17 is contained in a cup 19 of, e.g. tantalum, molybdenum, niobium or Hastelloy (Registered Trade Mark).

Title: Improvements in or relating to Infra-Red Radiation Control Devices
Inventor: AUTON JOHN PAUL
IPC: G02B5/20
Filed: 1966-09-05
Abstract: 1,196,245. Infrared radiation control device. MARCONI CO. Ltd. June 23, 1967 [Sept. 5, 1966], No. 39505/ 66. Heading G2J. A device for controlling the intensity of a polarized, parallel beam infrared radiation makes use of the principle of "frustrated total internal reflection" and comprises two fixed prisms 3, 4 and a prism 1 movable by a micrometer screw along the bisector of its apex angle E whereby the widths of air gaps 5, 6 are accurately variable simultaneously, the radiation beam entering and leaving the device at the Brewster angle. For an air gap of the order of one wavelength in width, the intensity of radiation transmitted depends on the ratio of the wavelength arid gap width, and the micrometer screw device may therefore be calibrated. The provision of two identical air gaps compensates for differences in internal reflection due to any lack of paralleism of the beam, which may be from a laser source. Silicon is a suitable material for the prisms.

Title: Electrically insulating layers
IPC: H01L29/78
Filed: 1972-08-30
Abstract: 1407222 Making semiconductor devices INTERNATIONAL BUSINESS MACHINES CORP 30 Aug 1972 [27 Sept 1971] 40157/72 Heading H1K An oxide layer is formed on an exposed surface of a silicon body by heating the body in an oxidizing atmosphere that includes, except if desired during the formation of a minor part of the thickness of the oxide layer immediately adjacent the silicon surface, sufficient additive such that at the temperature concerned, the layer, except the said minor part if present, is formed as a liquid and contains the additive as a dopant. The additive may comprise compounds of phosphorus and boron, which inhibit ion migration and which may be derived, for example, by adding POCl 3  or BBr 3  to the oxidizing atmosphere. The concentration of the additive in the oxide may be a few tenths of a mole per cent, but is preferably in the range 1À3 to 2À1 mole per cent. To prevent inversion at the semiconductor surface a minor part of the layer, e.g. 50, comprising the oxide without additive, is first formed on the semiconductor, or alternatively on opposite conductivity type additive may be added to compensate for any diffusion of the dopant into the semiconductor. In an example, chemically cleaned P-type Si wafers are preoxidized at 1000 C. in dry oxygen flowing at 800 cc. per minute for 4 minutes. The wafers are then exposed to a mixture of oxygen containing 0À8 parts per million POCl 8  for 19- 52 minutes. The resultant mixed SiO 2 -P 2 O 5  layers are formed as a liquid and may be 300- 500 thick. The method may be used to form the gate insulation of an IGFET.

Abstract: 1,272,124. Selective signalling. L.K.B. PRODUKTER A.B. 12 Aug., 1969 [12 Aug,. 1968], No. 40354/69. Heading G4H.  A liquid flow measuring system of the type in which a gas bubble is introduced P, Fig. 1, into the liquid and detected A at a fixed distance downstream to initiate the introduction of a further bubble and to add unity to a counter R, is characterized in that a further detector B is provided downstream from the first and used, in conjunction with the first, to prevent spurious bubbles in the liquid causing errors. In the first embodiment, Fig. 1, bubbles have to be detected simultaneously at the two detectors A, B in order to cause the introduction P of a further bubble. In a second embodiment, Fig. 2, a third detector C is added and bubbles have to be detected simultaneously at at least two of the three detectors A, B and C to cause the introduction P of a further bubble. This embodiment also includes a detector D adjacent the point of introduction of gas, which is used to turn off the supply of gas when a bubble extends from the point of introduction P up to the detector D. This embodiment is self-starting. In a third embodiment, Fig. 3, in addition to requiring the simultaneous detection of bubbles at two detectors A and B a further detector E is provided and the supply of gas P is kept on whilst the trailing edge of a bubble passes from detector E to detector A. This arrangement ensures that the length of liquid between two adjacent bubbles will be constant (equal to L-L, as shown) irrespective of how much the bubbles actually expand within the liquid due to pressure variations. This embodiment also is self-starting, and it also includes a further detector F so arranged that if a bubble is not introduced into the liquid when it should have been the flow of liquid is turned off 16 and a lamp 17 is extinguished.

Abstract: 1,193,984. Differential braking arrangements. AUTOMOTIVE PRODUCTS CO. Ltd. 20 Aug., 1968 [5 Sept., 1967], No. 40459/67. Heading B7H. [Also in Division F2] The invention provides a system for applying the brakes selectively to the wheels on one or other side of a vehicle, to assist in turning the vehicle. As shown, a hand lever 39 pivoted so as to operate in a plane transverse to the length of the vehicle is connected to an arm 38 which actuates a driver's brake-applying valve 10 (see Division F2) located between a master cylinder 34 and wheel brake cylinders 37 on opposite sides of the vehicle. In operation, with the arm 38 in its central position, as shown, liquid under pressure can pass from the master cylinder through both plugs 12 so that all the brakes on both sides may be applied simultaneously. If, however, before the master cylinder 34 is operated, the hand lever is moved, e.g. to the right, only the brakes on the right-hand side will be operated. When the master cylinder is actuated, and while the appropriate brakes are being applied, the ports and passages in valve 10 are such that arm 38 (and hence lever 39) is restored automatically to its central position. When the brakes are released the valve parts in valve 10 are symmetrically disposed, so that future actuations of the master cylinder will result in all brakes on both sides being applied, unless the hand lever 39 has been set for one-sided operation.
